Velocity dependent response of a piezoelectric element to hypervelocity microparticles

Evaluation of piezoelectric lead–zirconate–titanate multilayered detector by Fourier analysis

“…It was also found that the sensitivity was independent of the rotation speed. These results are useful for the application of PZT not only in a radiation and/or heavy-ion detector, but also in a space dust and/or space debri monitor on board a satellite [10][11][12]. On the other hand, further investigation is required to understand the production mechanism of the acoustic signal in piezoelectric PZT.…”

Effect of Heating and Cooling on the Piezoelectric Properties of a PZT Sensor for Mercury Dust Monitor

“…In comparison of the two components, the correlation between the output amplitude and the particle momentum is far better for the higher than the lower. In addition, Miyachi et al pointed out that a PZT element is free from external disturbances within a short period before the effects from reflected waves appear and an unperturbed portion of the first one cycle denoted as FOC can be regarded as the region representing "immediately after collision" 6) . From these reasons, the first one cycle of the higher frequency component is investigated in this paper.…”

“…Another promising physical property for the in-situ observation is momentum of each dust particle. Through electrostatic accelerator experiments, a good correlation has been found between particle momentum and the amplitude of the oscillational collision signal 5,6) . Our plan is to establish an empirical equation for the estimation of particle momentum from a signal form through calibration with electrostatic accelerators and a light gas gun.…”

Estimating the impact parameters of cosmic dust particles using a piezoelectric lead zirconate titanate detector

“…These experiments were conducted at the University of Tokyo and Max-Planck-Institut fü r Kernphysik (MPI-K), and the results obtained so far were as follows (described in full in Miyachi et al, 2003Miyachi et al, , 2004Miyachi et al, , 2005a. When the output voltage obtained from the PZT detector appeared immediately after the collision, it was found that the output waveform was explicitly related to the particle's velocity on impact.…”
